Servo Film 46 is a premium-grade, highly refined straight mineral oil designed specifically for use in oil film bearings, particularly in steel mills and other heavy industrial applications. Formulated from solvent-refined, high-viscosity index base oils, it offers superior oxidation resistance and excellent thermal stability, ensuring consistent lubrication even under demanding operating conditions. Its formulation allows rapid separation from water, making it ideal for environments where moisture contamination is a concern. This lubricant exhibits remarkable resistance to the formation of sludge and deposits, maintaining cleanliness within the system and ensuring smooth operation over extended service periods. Its balanced composition provides outstanding demulsibility characteristics, ensuring efficient removal of water and minimizing the risk of corrosion or lubricant degradation. Servo Film 46 maintains a high film strength, protecting critical components from wear and friction while promoting operational reliability. With excellent resistance to oxidation and thermal breakdown, Servo Film 46 delivers stable viscosity performance at elevated temperatures, helping reduce maintenance intervals and enhancing equipment life. It conforms to stringent performance standards including IPSS 1-09-001-81, Morgan Construction Co. USA specifications, and IS: 6552 – 1972 Grade 1 and 2, with minor deviation in pour point parameters. Servo Film 46 is ideally suited for use in oil circulation systems and steel mill bearing applications, as well as in machinery that requires non-additive type lubricants with high demulsibility properties. Its reliability, clean-running formulation, and thermal resilience make it a preferred choice for industries that demand consistent performance, protection, and longevity from their lubricants.
